1. SAFETY CHECKLIST

1.1 Confirm that the product to be stored is compatible with the tank and fittings.

1.2 Do not rigidly pipe tanks. Refer to section 5.3.2 for additional information.

1.3 Polyethylene tanks are designed and rated for ATMOSPHERIC PRESSURE ONLY. Proper venting alleviates pressure or vacuum from developing as the tank is filled or emptied. Venting should be sized to limit the tank to a maximum of 1/2 inch water column (0.018 PSI). Additional precautions may be required if the tank will be filled pneumatically (using air pressure). Review the chemical to see if it can be vented to the atmosphere or if it needs treatment prior to venting. Your application may need a sealed tank with a vent line to a scrubber system for proper chemical safety. FAILURE

TO PROVIDE PROPER VENTING WILL VOID YOUR WARRANTY.

1.4 WARNING: It is the installer's responsibility to follow all appropriate NFPA, OSHA, and gov ernmental safety precautions. The following information has been provided as guidelines for tank use and installation. It does not address safety issues which may be present at specific tank installation sites. Use appropriate safety practices when handling any tank and/or using heavy equipment.

1.5 Prevent excessive heat near or inside the tank. Standard polyethylene tanks are designed for a maximum continuous temperature of 100°F / 37.?°C. Consult factory for applications above 100°F / 37.?°C.

1.6 Consider tank entry as a confined space entry. Follow proper entry procedures.

1. 7 Do not stand or work on top of a tank. The surface is flexible and slippery and a dangerous fall could occur. There is no weight or load rating for the tank dome. Remember - Safety First!

1.8 Read all warning labels on the tank prior to use and installation.

1.9 Record all warranty information as per section 2 while all information is available at time of tank receipt. Please refer to section 10 for warranty and policy statements.

3. RECEIVING AND INSPECTING YOUR TANK

3.1 Upon arrival at the destination, the purchaser and/or his agent shall be responsible for inspection for damage in transit. If damage has occurred or parts are missing, the purchaser should document this on the bill of lading, file a claim with the carrier, and notify the manufacturer prior to putting the tank into service.

3.2 Verify that the tank part number on the packing slip matches the tank bar code being delivered.

3.3 Do not drop a tank off a truck onto the ground. Please see section 4 for proper unloading instructions.

3.4 Please match tank components to bill of lading. Some tank components may be shipped inside the tank. Remove any components shipped inside the tank before putting the tank into a vertical position. Loose items that are installed in side the tank can be fitted up before the tank is put into a vertical position.

4. TANK LOADING, UNLOADING, AND POSITIONING

4.1 HORIZONTAL TANKS

4.1.1 Tanks shall be wrapped if ordered by the customer.

4.1.2 Tanks should be hand carried, moved with a handling cart, or moved with a forklift with protected or rounded fork extensions (to prevent sharp forks from damaging tanks and to provide adequate support for the tank as it is being moved).

4.1.3 Tanks should be loaded and unloaded from a horizontal position in the truck with a minimal amount of sliding. The tank shall be hand carried, moved with a handling cart, or moved with a forklift with protected or rounded fork extensions to minimize sliding.

4.1.4 Tanks should be loaded or unloaded from a dock of proper height or with a forklift with protected or rounded fork extensions. NEVER drop a tank off of a truck onto the ground since this may damage the tank and void the war ranty.

4.2 SMALL VERTICAL and CONE BOTTOM TANKS (LESS THAN 2000 GALLON CAPACITY)

4.2.1 Tanks shall be wrapped if ordered by the customer.

4.2.2 Tanks should be hand carried, moved with a handling cart, or moved with a forklift with protected or rounded fork extensions (to prevent sharp forks from damaging tanks and to provide adequate support for the tank as it is being moved).

4.2.3 Tanks should be loaded and unloaded from a horizontal or vertical position in the truck with a minimal amount of sliding. The tank shall be hand carried, moved with a handling cart, or moved with a forklift with protected or rounded fork extensions to minimize sliding.

4.2.4 Tanks should be loaded or unloaded from a dock of proper height or with a forklift with protected or rounded fork extensions. NEVER drop a tank off of a truck onto the ground since this may damage the tank and void the war ranty.

4.2.5 If a tank is to be stored for over one month before being put into service, it should be stored in an upright vertical position. Cone bottom tanks should be stored upright in their appropriate cone stand. Tanks stored outdoors must be se cured to prevent movement or being overturned in high wind situations.

4.3 LARGE VERTICAL and CONE BOTTOM TANKS (GREATER THAN OR EQUAL TO 2000 GALLONS)

4.3.1 Tanks shall be wrapped if ordered by the customer.

4.3.2 Tanks should be moved, loaded, and unloaded in a horizontal position with a forklift with protected or rounded fork extensions, or with a crane with a spreader bar and 2 slings of appropriate size positioned on each tank as shown in Figure 4.3.2 NEVER drop a tank off of a truck onto the ground since this may damage the tank and void the tank warran ty.

4.3.3 Tank lifting lugs are intended for moving the tank from a horizontal position to a vertical position from a firm sur face. Lifting lugs must not be used to load or unload tanks from trailers. This is a dangerous situation since the tank could roll off of the shifting trailer surface as the load is being moved.

4.3.4 After the tank has been placed on a firm , level surface in a horizontal position, the lifting lugs may be used to erect the tank in a vertical position on an appropriate support pad. The tank should be lifted using a symmetrical ar rangement of lugs to disperse the load evenly throughout the tank. To properly attach to the lifting lugs a straight clevis should be used with a minimum open throat distance of 1-1/2" and 1" diameter pins. A minimum of 4 lugs should be at tached with equal length cables on all large vertical tank sizes except 142" diameter tanks. 142" diameter tanks require 3 lugs to be attached. All tanks should be positioned with 2 lugs closest to the ground prior to lifting the tank to the vertical position. Refer to Figure 4.3.4 for additional information. If the tank does not have lifting lugs, it may be necessary to rig the tank with slings or use a pipe and chain through the tank manway to upright the tank. Please contact the factory for additional information as necessary.

4.3.5 If a tank is to be stored for over one month before being put into service, it should be stored in an upright vertical position. Cone bottom tanks should be stored upright in their appropriate cone stand. Tanks stored outdoors must be se cured to prevent movement or being overturned in high wind situations.

4.4 INSULATED TANKS (ADDITIONAL INSTRUCTIONS)

4.4.1 Insulated tanks must be moved with devices that have large padded contact surfaces to prevent damage to the foam insulation. NEVER allow the tank to drop or roll on rough surfaces as this may damage the foam insulation.

When transporting foam insulated tanks, use 4" wide nylon straps and slings to move and secure the tanks. This will as sist in decreasing the stress on the foam that can be caused by narrower straps.

4.5 CAPTOR CONTAINMENT TANKS (ADDITIONAL INSTRUCTIONS)

4.5.1 Captor containment tanks are shipped assembled (primary tank inside of containment tank) with a shipping cable assembly holding the two tanks together. Make sure the UFO bellows assembly didn't come off center due to the primary tank rotating or shifting during transit or offloading. Lift and position the tank as per previous instructions. Once the tank is in position, remove the shipping cables from the tank. Do not leave the shipping cables under the tank. Follow standard vertical tank restraining methods shown in section 8.2 to restrain the tank assembly for wind or seismic conditions.

5. PRE-INSTALLATION NOTES

5.1 TANK OPERATING CRITERIA

5.1.1 TEMPERATURE - All standard SI I tanks are designed for a maximum continuous service temperature of 100° F.

Service temperatures greater than 100° F reduce the strength of the tank. Applications with temperatures greater than 100° F require greater wall thickness to accommodate this reduction in strength. Please consult factory for applications with service temperatures greater than 100° F.

5.1.2 PRESSURE - All standard SIi tanks are designed for use at atmospheric pressure. Pressure or vacuum situa tions can cause excessive deformation or damage to the tanks and void warranty. Please consult factory for appli cations which may develop pressure or vacuum situations.

5.1.3 CHEMICAL COMPATIBILITY - Suitability of the tank assembly (tank, fittings, gaskets, etc.) for storing a particular chemical must be confirmed by chemical data (this should have been done by the tank distributor or the end user prior to placing the tank order). However, changes to the tank (i.e. tank accessories, or the service of the tank) can occur. Please consult the factory with any questions.

5.1.4 LOCATION REQUIREMENTS - There may be location requirements which should be considered prior to placing the tank into service. Some items to consider are: secondary containment; locating the tank in a flood plain; locating the tank so it is easy to install and access for service; locating a tank in an area where seismic or wind forces may be experi enced; heat from surrounding equipment; and the ability to remove and replace tank in the future. It is the responsibility of the end user to ensure that all location requirements have been taken into consideration. Check for all federal, state, and local regulations that may apply to the tank installation. A thorough evaluation of the proposed tank location pri or to tank installation is recommended.

5.1.5 TANK ENTRY PRECAUTIONS - If entry into the tank is necessary, be sure to take all necessary precautions and follow all applicable regulations. Entry into a tank should be considered a "CONFINED SPACE ENTRY'' with appropriate OSHA safety precautions required. There are many safety practices which should be considered depending on the specif ic conditions at the site. Please follow all local, state, and Federal rules and regulations.

5.1.6 GALLONAGE MARKINGS - Level markings on the tank or on gallon decals should be considered nominal meas-urements and are not intended for precise measuring or metering.

5.1.8 BASIC CLEANING - Basic cleaning of the tank requires the use of a pressure washer with a mild detergent and water temperature up to 130°F / 54 °c

5.1.7 GOUGE REMOVAL - Should your tank get gouged during shipping or off-loading it may be repaired using the gouge removal procedure - refer to figure 5.1.

5.1.8 HYDRO TEST - The tank should be hydro tested (water test) for 24 hours before the introduction of chemical. If necessary, remove all test water to prevent any possible reaction with the chemical to be stored.

5.2.1 Vertical flat bottom tanks should be positioned on a concrete pad providing adequate support and a method to at-tach a tank restraint system (see Section 8 for restraint system pad placement criteria). The pad should be clean, smooth, and level so it fully supports the entire tank bottom with no deflection. The construction site engineer must design an ap propriate concrete pad based on the specific application. FAILURE TO PROVIDE PROPER FOUNDATION AND SUPPORTS WILL VOID WARRANTY. A sand mound support can is to be placed under the tank bottom to promote tank drainage and extend tank life in certain applications. This is recommended for all single wall vertical tanks 10,000 gallons and larger (not recommended for double wall Captor tanks). The sand should be a construction grade utility sand or finer.

The tank and pad placement must be done to prevent any erosion of the sand from under the tank. Please refer to Figure

5.2. The sand mound must be very uniform without lumps or foreign objects. Per the chart in Figure 5.2, draw a circle on the tank pad and rake the sand uniformly with zero elevation at the circle perimeter and an elevation in the center per the chart in Figure 5.2. The chart recommendations are nominal dimensions. The best support is a sand mound that follows the normally convex shape of the tank bottom. If the tank bottom is not as convex as the dimensions shown for the sand mound in Figure 5.2, then follow the tank bottom. Adjust the sand mound shape/size so the tank has minimal contact with the sand when properly centered on the mound.

5.2.2 Vertical flat bottom tanks with SUMO fittings may require a notch in the concrete support pad just in front of the SUMO fitting for piping and piping accessories. The SUMO fitting has a ±5° tolerance for fitting projection off horizontal.

Since the SUMO fitting comes out from the tank very near ground level, concrete support pads which project past the SUMO fitting may interfere with the SUMO and/or its piping accessories. SIi recommends that the support pad be notched to provide adequate clearance for piping and tank expansion/contraction movement. Please refer to Figure 5.3.

5.2.3 Cone bottom or horizontal tanks require specifically designed support structures. Inadequate or improperly de-signed support structures may cause premature tank failure. Therefore, any support structure that is not of SIi manu facture must be approved by SIi in writing or ALL WARRANTIES WILL BE VOIDED i-----~,__I __________ A--------------

5.3.1 Most tank fittings are typically left installed in the tank. Some fittings are not installed due to damage potential or customer request. Customer job site fitting installation insures proper gasket compression and minimizes fitting damage potential. This is because even the fittings installed at the factory may become damaged or loose during shipping and they need to be readjusted or retightened per section 6. Some distributors sell or install their own tank fittings or accesso ries. These fittings or accessories are not warranted by SIi.

5.3.2 Tank connections must have adequate provisions for tank expansion/contraction due to temperature and load changes. See Figure 5.4. The overall height of the tank will shorten during filling. Therefore on the top dome of the tank, the piping to top fitting connections must be allowed to move with the tank or flexible connections may be used. Rigid pip ing must not be directly plumbed to tank sidewall connections. Provisions must be made that allow 4% dimensional movement on sidewall connections. SIi requires using flexible hose, expansion joints or other provisions for all tank side wall connections. Please see the hose connection examples in Figure 5.5. SIi has developed the Flexmaster expansion joint for 2" and 3" bolted tank connections. Please see section 7.11 for more details. The use of rigid piping or the failure to provide for the expansion of the tank will void all warranties.

5.3.3 FITTING INSTALLATION GENERAL GUIDELINES - If fittings are to be customer drilled and installed, there are some general installation guidelines which may be helpful.

5.3.3.1 LOCATION - It is very important that fitting location be carefully considered prior to cutting any holes. SIi recom mends (fitting size dependent) a 6" minimum centerline height for fittings on tanks less than 3000 gallons with the fitting gasket at least 1-1/2" above or below the end of any tank knuckle radius. SIi recommends (fitting size dependent) a 9" minimum centerline height for fittings on tanks 3000 gallons or larger with the fitting gasket at least 3" above or below the end of any tank knuckle radius. SIi recommends locating all fittings so gasket seal areas do not go through any tank flange lines or any molded-in tank feature (i.e. gallonage markers, logos, ribs, edges of tank flats, etc.). SIi does not recommend field cutting and installation of fittings on insulated tanks. Fittings must be located to avoid interference with tie-down devices and to allow for tightening of fittings nut(s). Mark all of the proposed fitting locations with a marker. Re-inspect all of the locations prior to cutting any holes.

5.3.3.2 TOOLS - It is very important to obtain the correct tools before attempting to install any tank fitting. Tools you will need for installing tank fittings properly include:

*Marker for laying out holes *Tape measure, straight edge, plum-bob (to align fittings meant to be aligned), etc.

*1/2" drill motor *Hole saw sized to the O.D. of the fitting body if bulkhead style (see section 6.1, and 6.2).

*Hole saw sized to the I.D. of the fitting flange hole or the same size as the fitting's size if flange style (see section 6.3, and 6.5).

*Drills for any bolt holes (size +1/16" larger than the size of the bolts) *Deburring tool (a drum sander and 150 - 220 grit sandpaper may also be used) *Wrenches (adjustable, sockets, strap wrench, etc.)

5.3.3.3 PROCEDURE

1. Disassemble the fitting and use it as a final location check as noted in 5.3.3.1.

2. With the center hole marked, cut the tank hole using the correct size hole saw (see 5.3.3.2).

3. If the fitting is a flange style (see section 6.3 and 6.5) then mark one of the bolt holes using the outer flange.

The bolt holes should be oriented so the bolt holes straddle the principal centerline of the tank. With the hole correctly lo cated and marked, drill the bolt hole.

4. Temporarily install one bolt and position the flange over the main fitting hole.

5. Mark the bolt hole opposite the bolt hole already drilled and drill that bolt hole.

6. Temporarily install another bolt and drill the remaining bolt holes using the flange as a guide.

7. With all of the fitting's holes drilled, gently deburr the hole(s) with the deburring tool. Do not put any nicks or scratches into the tank. Sand any nicks or scratches out with sandpaper greater than 120 grit.

8. Clean away any debris from the sealing surface of the tank.

9. For tanks greater than 1/2" thick, measure the tank wall thickness. If the wall thickness is not consistent within± 1/32" around all of the fitting hole(s), some sanding on the inside of the tank wall will be necessary. This must be done carefully and as little as necessary. The purpose of the sanding is to make the wall thickness even, not to create a flat on the tank wall. The final finish sanding should be done with greater than 120 grit sand paper (preferably 220 grit).

10. With all of the fitting's hole(s) prepared, install the fitting using the instructions from the appropriate section (6.1, 6.2, 6.3, or 6.5). The inside tank wall surface must be clean and smooth at time of fitting installation.

5.4 TESTING AND FINAL INSPECTION

5.4.1 After all fittings are installed and all connections to the tank have been made, fill the tank with water and hold for at least 5 hours to identify any leaks. A record of the water pre-test must be submitted to SIi to validate the tank warranty.

5.5 ACCESSORY PARTS

5.5.1 Various parts must be packaged separately to prevent damage during transportation. These parts are usually bagged or boxed to prevent loss or damage. Some parts may be shipped inside of the tank.

6. FITTINGS

NOTE: The following installation instructions assume the tank has been predrilled and prepared for fitting installation by the factory. Most fittings are factory installed, but check fittings for damage and gasket compression. See section 5.3 for general tank fitting information if a fitting is to be installed without a factory prepared location. Prior to installing fittings, check the sealing surface for debris and/or scratches which could cause leakage.

6.1 THREADED BULKHEAD FITTING

6.1.1 Remove the nut (C) from the fitting body (A) and gasket (B). See Figure 6.1 for part identification.

,,----,-----,------....,------------< A

INSIDE TANK WALL SURFACE

Figure 6.1

6.1.2 Working from inside the tank, slide the fitting body (A) through the hole in the tank. The gasket (B) should be be tween the fitting body flange and the inside tank wall. Install the nut (C) on the fitting threads protruding on the outside of the tank.

6.1.3 To obtain proper gasket compression for bulkhead fitting installation, tighten the fitting nut hand tight (check to see if it engages the tank wall). Tighten the nut an additional 3/4 turn for fittings less than 1 in. , or 1/3 turn for fittings 1 in.

or larger. Anti-seize is recommended to prevent thread seizing on bulkhead fittings. Inspect the gasket to make sure it is fully contacting the inner surface of the fitting body flange and the inside tank wall. Gasket compression should be be tween 25 - 50%. Recheck fitting tightness periodically.

6.2 SELF-ALIGNING THREADED BULKHEAD FITTING

6.2.1 Follow the same procedures as detailed under threaded bulkhead fitting installation steps 6.1.1 - 6.1.3.

6.2.2 Piping should be installed into the fitting ball with an appropriate thread sealant (i.e. Teflon pipe sealant). Adjust the piping to the required angle (within the limits of the fitting). When the piping has been located as required, tighten the PVC ball retainer ring located on top of the PVC ball.

6.3 BOLTED FLANGE FITTING

6.3.1 The bolted flange fitting shall be constructed with 2 ea. 150 lb. flanges (C1 and C2), 2 ea. 150 lb. flange gaskets (D1 and D2), the correct number of full threaded bolts (A), bolt gaskets (B), flat washers (E), lock washers (F), and hex nuts (G) for the flange specified. NOTE: If the tank wall thickness is greater than or equal to 0.75", fittings with stainless steel bolts will require longer bolts for installation. Consult with the factory for the correct part number when ordering long bolted flange fittings. Refer to Figure 6.2 for part identification.

6.3.2 Disassemble the fitting as shipped by removing the bolt's hex nuts, lock washers, flat washers, outer flange, and outer flange gasket. Locate the fitting hole on the inside of the tank and insert the bolts (still installed on the inner flange and gasket) through the drilled holes in the tank. Place the outer flange gasket over the bolts on the outside surface to the tank. Place the outer flange over the outer gasket and bolts. Install the flat washers, lock washers, and hex nuts on the bolts. Check to make sure the fitting assembly appears as shown in Figure 6.2.

6.3.3 To obtain proper gasket compression, tighten all the fitting nuts hand tight with a deep socket using the bolt tight ening sequence shown until the gaskets engage the tank wall and the lock washers are compressed. Tighten each nut an additional 3 turns (2 turns if the inner flange and gasket are not utilized) using the same sequence (do not tighten more than 1 turn at a time). A light application of lubricating oil is necessary to prevent thread seizing on S.S. bolts. Gasket compression should be between 25 - 50%. While gasket compression needs to be the controlling factor to obtain a proper seal, do not apply more torque than recommended by the flange manufacturer. See torque value listed on flange. Re check fitting tightness periodically.

6.4 BOLTED STAINLESS STEEL FITTING

6.4.1 The bolted stainless steel fitting shall be constructed with 1 ea. inside flange with studs (A), 1 ea. fitting gaskets (B), 1 ea. outside flange (C), and the correct number of lock washers (D), and hex nuts (E) for the fitting specified. Refer to Figure 6.4 for part identification.

6.4.2 Disassemble the fitting as shipped by removing the hex nuts, lock washers, and outside flange. Locate the fitting hole on the inside of the tank and insert the fitting's studs through the drilled holes in the tank. The flange gasket (B) should be between the inside fitting flange and the inside tank wall. Place the outside flange over the studs on the out side surface of the tank. Install the lock washers and hex nuts on the studs. Check to make sure the fitting assembly ap pears as shown in Figure 6.4.

6.4.3 To obtain proper gasket compression, tighten all the fitting nuts hand tight with a deep socket using the bolt tight ening sequence shown until the gasket engages the tank wall and the lock washers are compressed. Tighten each nut an additional 1 - 2 turns using the same sequence (do not tighten more than 1 turn at a time). Do not apply more than 15 ft . -lbs. of torque. A light application of lubricating oil is necessary to prevent thread seizing on S.S. bolts.

6.5 SNYDER UNITIZED MOLDED OUTLET- (SUMO™) (PATENT NO. 5,374,026)

6.5.1 The SUMO fitting shall be constructed with 1 ea. smaller o-ring (A), 1 ea. larger o-ring (B), and 1 ea. SUMO adapter (C). Refer to Figure 6.5 for part identification. NOTE - The tank is shipped with a shipping stabilizer installed in the SUMO outlet. NEVER move the container without the shipping stabilizer installed.

6.5.2 Once the tank has been properly placed on its foundation, remove the shipping stabilizer and clean away any dirt or debris from the SUMO outlet threads and o-ring seats. Use only a soft moist cloth . NEVER USE A TOOL THAT

COULD SCRATCH THE O-RING SEATS.

6.5.3 Install the smaller o-ring inside the SUMO molded-in fitting. Make sure it is placed in the o-ring seat area evenly.

Carefully stretch the larger o-ring enough to install it on the SUMO adapter. Only a SIi SUMO adapter may be used. Use of a non-approved adapter may damage your tank outlet and will void the tank warranty. Theo-ring may be lubri cated with a suitable lubricant such as water. Do not use silicone or Teflon sealants. Screw the adapter in until the step on the adapter is flush with the tank wall. Do not over-torque the adapter (25 ft. - lbs. of torque maximum). Figure 6.5 shows a sectional view of an assembled SUMO fitting .

6.5.4 Once the SUMO adapter is installed, other components may be attached to the adapter. A union or flange adapt-er with a flexible expansion joint should be installed as close to the tank as possible to allow for future disassembly. The SUMO fitting must have adequate clearance for any piping accessories and allow for a ±5° outlet angle change. Consult factory for pad and/or accessory clearance questions. A notch in the tank support pad may be necessary (see Figure 5.2).

6.6 SIPHON TUBE FITTINGS

6.6.1 Siphon tubes may be added to the fittings specified in sections 6.1, 6.3, 6.4, and 6.5. Siphon tubes shall be cus-tomer installed with the tank in a vertical position after fitting installation.

6.6.2 PVC and CPVC siphon tubes need to be solvent welded with the proper solvent cement into the socket of a pre-viously installed fitting. Threaded siphon tubes need to be threaded in place with Teflon pipe sealant applied to the threads prior to the fitting being installed.

7.2 MANWAYS /VENTS-AIR SURGE

7.2.1 The air surge manway (fig 7.2.1) is used in pneumatic fill applications, it provides additional venting (it should never be the main vent) that the primary vent source cannot handle. Installed by running a bead of 3/16" silicone sealant on the underside of the ring (where the screw holes are located). Then place the ring into the opening, once oriented in the direction desired use a screw gun and run 8 each #10 S.S. screws through the small holes in the ring and into the tank. Do not over torque the screws as it may damage the tank, ring, or screws.

7.8 REVERSE LEVEL SIGHT GAUGE (SIDEWALL SUPPORTED - WITH SADDLE CLAMPS)

7.8.1 The component parts (except the rope) have been cut to meet SIi and customer specifications. The sight gauge shall be supported at 5 ft. maximum intervals to the liquid holding tank with the support structures provided.

7.8.2 Assemble the piping loosely using Figure 7.7, the guidelines detailed below, and the customer approved tank drawing to ensure all parts are present and cut to length. As soon as all parts have been checked, assemble the parts with solvent weld cement and/or threaded connections as shown in Figure 7.7. NOTE - Do not use solvent weld cement on the outside joints indicated in Figure 7.7. SIi recommends periodic inspection of the rollers in the tee assemblies and the rope to ensure proper operation of the gauge. If it is a requirement to seal these joints, a silicone based caulking should be sufficient.

7.8.3 Assemble and install the support structures as shown in Figure 7.7 (without the saddle clamp cover caps and clips). Make sure the support clamp orientation is correct (with the small width of the wedge toward the top of the tank) and that the plugged support pipes are installed with the plugged end as close to the support fitting as possible. Make sure that the indicator board has been installed over the outer pipe supports as shown in Figure 7.7. Assemble and install piping as per the customer approved drawing. As piping is being installed on the tank, lock it in place with the saddle clamp cover caps and clips provided (make sure that the sealing o-ring is in the proper position as the pipe is positioned into the saddle support body). Seal all threaded pipe connections with Teflon pipe sealant and connect solvent weld sock ets with the correct solvent cement (except the joints as noted in Figure 7.7).

7.8.4 With the inner and outer tank pipes in place, connect the rope provided to the tank float (This is accomplished by threading the rope through the center hole in the float and out one of the side holes, double knotting the rope, cutting off any excess material and pulling the rope back so the knot holds under the center hole) and lower it into the inner pipe as shown. Thread the rope through the tee assemblies and the connecting pipe as shown. At this point the float should be at the bottom of the tank, the tee assemblies and connecting pipe should be assembled and sitting off at an angle from the outer clear 2" PVC pipe. With the rope threaded through the outer tee assembly, attach the rope to the indicator in a posi tion parallel with the zero mark on the indicator board. (This is accomplished by threading the rope through the center hole in the indicator, double knotting the rope, checking the indicator position, adjusting as necessary and cutting any excess material protruding from the bottom of the indicator.) Put the indicator into the outer clear 2" PVC pipe while swinging the tee assemblies and connecting pipe into position. With all piping and tee assemblies installed, install the 3" PVC pipe plugs. During the tank hydrotest and first operations of the tank, check the gauge for proper level indication and adjust as necessary. NOTE - This is a gallonage indicator and is not intended as an accurate measuring device.
